The macro container_of from kernel.h performs the same
pointer arithmetic operation.

The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)

// &lt;smpl&gt;
@@
type T;
expression mptr;
expression member;
@@

- (void *)((char *)mptr - offsetof(T, member))
+ container_of(mptr, T, member)
// &lt;/smpl&gt;

It is possible for the CPU to re-enable it's interrupt block bit
before the write to the interrupt controller has actually masked out
the external interupt at the controller. We get around this by
reading back from the interrupt controller which will ensure the
write has happened.

Now that the dependent patches are merged, we are ready to enable
sparseirq support. This simply adds the Kconfig option, and then converts
from the _cpu to the _node allocation routines to follow the upstream
sparseirq API changes.

irq_to_desc_alloc_cpu() has been renamed to irq_to_desc_alloc_node() in
-next, but as we can not presently enable SPARSE_IRQ without the early
irq_desc alloc patch, protect it with an ifdef until the interface has
settled and we are ready to enable it system-wide.

<title>sh: irq: Teach ipr and intc about dynamically allocating irq_descs.</title>

This hooks in irq_to_desc_alloc_cpu() to the necessary code paths in the
intc and ipr controller registration paths. As these are the primary call
paths for all SH CPUs, this alone will make all CPUs sparse IRQ ready.

There is the added benefit now that each CPU contains specific IPR and
INTC tables, so only the vectors with interrupt sources backing them will
ever see an irq_desc instantiation. This effectively packs irq_desc
down to match the CPU, rather than padding NR_IRQS out to cover the valid
vector range.

Boards with extra sources will still have to fiddle with the nr_irqs
setting, but they can continue doing so through the machvec as before.
